<p>M673L2Service Side DC wire harness plug-in. Vibration isolated junction box has AC terminal strip, DC breaker, 30 amp AC breaker and solid state AC automatic voltage regulator. Cast valve cover/intake manfold with oil ll and washable air lter. Sound Maze air intake has an acoustic chamber and formed hose to reduce valve train and intake pulsation noise. Bosch type in-line injection pump.</p> <p>60 Hz / 1800 RPM</p> <p>6 kW 5 kW</p> <p>50 Hz / 1500 RPMThe ideal 6kW generator set is small and lightweight. The M673L2 certainly qualies. But it stands apart through its remarkable long-life reliability. The reason? The M673L2 runs at 1800 rpm (1500 rpm for 50 Hz), instead of 3600 rpm. Consider that during only 2000 hours of operation the 1800 rpm M673L2 will turn 216 million fewer revolutions than a 3600 rpm set. Its pistons will travel 38,522 fewer miles. Its cylinders will withstand 108 million fewer detonations. Which engine do you think will give more years of reliable service? We couldnt agree more. The M673L2 has a balanced Lugger three cylinder diesel instead of a rough two banger. Four plateform isolation mounts reduce vibration transmission even more. For maximum comfort afloat the new M673L2 has a Sound Maze air intake system. Air enters through a molded rubber hose and an acoustic dampening chamber. Air goes in but much less noise gets out. For maximum sound attenuation, specify a sound enclosure. It is only 32.5 inches long and has powder-coated aluminum panels with trigger latches for easy service access. The generator s automatic voltage regulator is powered by an auxiliary AC stator winding that isolates it from the main windings. The AVR always has clean power to provide excitation for faster load response and better motor starting. Your air conditioner and other motor driven equipment will love being matched with the 673. A 30 amp AC circuit breaker in the junction box protects your wiring. Safety shutdowns for low oil pressure, high coolant temperature and high exhaust temperature protect your engine. The M673L2 meets US EPA Tier II emission standards. You, your moorage neighbors and the environment will all benet. 1800 rpm reliability, low emissions, quiet operation and strong motor starting.
